Some torrents does not download

[untitledlt]

What version of WebTorrent?
0.102.4

What operating system and Node.js version?
OS X Mojave, node.js: v10.13.0

What did you expect to happen?
Torrent download should start

What actually happened?
Torrent gets added but download does not start.

Some torrents do not download. They get parsed but download does not start. I know what Webtorrent requires torrents to be seeded by WebRTC compatible clients but i can download those torrent in Webtorrent Desktop app. I guess it has the same limitations but does not have this problem.

I have a listeners on error and warning events but nothing comes here.
Let me know if you need more info.
.torrent file can be provided personally.

it's a node.js app

Is the torrent webrtc seeded, tcp/udp seeded, or both?

[untitledlt]

How can i check that?

[untitledlt]

So WebRTC seed is only required for running webtorrent in browser?
I've just tried webtorrent-cli and it works. Node.js app still says 0 peers.

update: found one torrent which works in Webtorrent desktop app but doesn't work in node.js app nor webtorrent-cli.

[DiegoRBaquero]

Correct. And maybe there are torrents which are only seeded in one network, so trying on the other won't work.

[untitledlt]

Not that case. Webtorrent Desktop works on the same machine.

Webtorrent Desktop doesn't actually have that same limitation. It acts as both a traditional bittorrent client and a webRTC webtorrent client. It can use webRTC and/or UDP/TCP to download torrents, so it can download a torrent seeded by a browser and it can also download a torrent seeded by something like transmission or utorrent.

webtorrent-cli only uses the webRTC protocol, while webtorrent-hybrid uses both.

The Webtorrent library (via npm) only uses the webRTC protocol in browsers, and only uses the TCP/UDP protocol in node.js. (depending on whether it's browserified or not)

Thanks for your answer.
Is it possible to use both protocols (webRTC and tcp/udp) in node.js app?

[KayleePop]

Yeah, use webtorrent-hybrid

We are experiencing this as well, is there anything new regarding this ?
